No - the one thing the trucking company is hoping you never find out is that a lot of truck crash evidence can be demanded and preserved, and destroying it after notice can create serious problems for them.

The exceptions and edge cases are what make this more complicated:

• Some data is kept only briefly unless someone acts fast. Under FMCSA rules, electronic logging device records and related hours-of-service data are generally kept for 6 months. But dashcam video, inward-facing camera footage, GPS pings, Qualcomm messages, and engine control module data may be overwritten much sooner under a company's internal policy.
• Not every company in the chain has the same records. The driver may have trip documents, the motor carrier usually has safety files and ELD data, and a broker often has dispatch and contract records but not the truck's black-box data. In a winter wreck on the Broken Arrow Expressway, I-44, or US-169 involving black ice or low visibility, that distinction matters.
• Some vehicles are not under the same federal rules. A smaller intrastate truck, municipal vehicle, or certain local service vehicle may not have the same FMCSA recordkeeping duties as an interstate carrier.
• Evidence can still disappear before anyone sends a preservation demand. Salt trucks, delivery vans, and semis involved in cold-weather Tulsa crashes are often repaired and put back on the road quickly.
• Workers' comp and a truck claim are separate. If a nurse, teacher, or hospital worker was hit while working, the job injury may go through the Oklahoma Workers' Compensation Commission, but a claim against the trucking company is a separate third-party case.
• Deadlines still matter even if evidence is destroyed. Oklahoma's general personal injury deadline is 2 years from the crash date, but key trucking evidence should be pursued far earlier than that.

What people call "erasing the logs" is often really automatic overwriting, which is exactly why early preservation of ELD, dashcam, inspection, maintenance, and dispatch records matters.
